ANGLING-MACHINE.

To aZZlwhom it may concern;

Beit known that I, DANIEL, J L MU NANE,

a citizen of the United States, residing at lChicagoHeightsfln the county of Cook and State'oflllinois', have invented a new and useful Improvementin Angling-Machines, ofswhich, the following is a specification,

-My invention relates more particularly to apparatus of thegeneral character above stated, forsprea-ding the sides of metal mold- T ing to-cause them; to vassume the desired angular relatioirto each other, forflefiecting thedesired fit of the molding to theparts with-which itis assembled, as, for example,

in store frontconstructions, where, under.

varying conditions, the angle presented by; the sides, of the moldingvaries from ap proximately ninety degrees to, one hundred and forty degrees; It may be further stated that in practice it is not commercially feasithestructure, the sides of the molding should extend at a predeterminedangle, depending upon the particular condition presented, as

distinguished from alcondition wherein the sidesof the molding may extend relative to :each other approximately at a certain angle andsa margin of a number of degrees is allowable, this condition rendering highly desirable the provision of means whereby a molding may be spread with accuracy to the desired angle,

,My object generally stated is to provide a 7 novel, simple and economicalvdevice, for the purpose above stated, whichmay befidJllSted' quickly and accurately to effect the spreadingof the molding to the desired angle, whereby the operator upon settingthe machine to produce the spreading of the molding, insuresthe spreadingof the molding to the desired angle, this feature of the machine permitting unskilled workmen to readily spread the molding to the desired angle and without danger of waste of the material e vReferring to Specification of Letters Patent the. accompanying drawings,,Figure 1 is a plan view of my 1m- Patented July 2,1918.

proveddevice showing it applied to operatiyeposition on a bench. I Fig, 2 is a section taken the 1rregular lines 2 on Figs. 1 and 3 andv ewed 1n the direction of the arrow;

and Fifg.- 3, a section taken at the line3on Fig. Is and viewed in the direction of the arrow. A

; In accordance with thepreferred embodi- I ment'of my invention, thedevice is adapted, 1n v ew of the conditions; under vwhich would be commonly used, to beclamped to a benchor table, the top of which is repre- I sented fat a. .To this end the body portion 5 of the device, whichmay be a casting, is

provided at its lower end with a pair of jaws '6 and"7,the jaw 7 containing athreaded opening in which screws a set-screw ,8, adapted to engagethe underside offthetable land clampthe latter between the set-screw 8 and the jaw 6. J ournaled'in an opening '9 in the body 5 of the deyice, to extendabove the table-tops, is a shaft 10, which is pro: vided near one end with a collar 11 opposing one end of the member aiand with a reduced threaded-portion l2, affording a shoulder 13 adjacent the opposite end of the member 5. The shaft 10, in the construction I illustrated, is adapted to be rotated by, means of a crank-handleH which screws upon thethreaded-end 12 of: the shaft lOand against theshoulder 13, a nut 15 screwing upon this end of the shaft 10 and against "a washer 16 interposed between the handle 14 andthe nut. The end of the shaft 10 opposite to that equipped with the handle 14 has rigidly securedthereto a roll 17, this" roll being releasably held to the shaft 10 the wing-nut18, the periphery of the 'roll 17,

by preference, having the annular flanges 19 at its opposite edges as represented.

Cooperating with the roll 17, in a manner hereinafter described, is a roll 20, havingiits periphery shaped to conform to the outer side of themolding, for example, as shown at 21. The roll 20 is rigidly secured on an end ofa shaft 22extending parallel with," and above, the shaft 10, as by clampingthis roll between a collar 23 on the shaft and a washer 24: surrounding the threadedend 25'of the shaft and backed by. a wingnut 26 screwing upon the threaded portion 25 of the shaft.

Thev end of the shaft 22 opposite the end which carries the roll 20 is journaled at ballbearings 27 and 28 in a sleeve 29 which extends through and is rotatably adjustable in a bore 30 provided in the upper end of the member 5, the shaft 22 being eccentrically disposed relative to the sleeve 29, as clearly represented in Fig. 2, it being readily understood from the foregoing that by rotatably adjusting the sleeve 29 in its bearing, the roll 20 will be adjusted toward, or away from, the roll 17, as the case may be.

For convenience of operation, the member 5 has secured thereto, as by the bolt 31, oppositely-extending arms 32 which project from the member 5 at angles to the axes of the shafts 10 and 22 and are provided at theirextremities with upwardly-extending pins 33, spaced apart, as represented in Fig. 1.

In the use of the device the molding to be spread, as, for example, the molding rep- 7 resented atf34, is introduced atone end into the space between the rolls 17 and 20, to engage, at its upper central surface 35,

with the portion 21 of the roll 20, and at its marginal edges with the periphery of the roll 17, the pins 33 serving as guides for the "strip. Upon rotating the shaft 10, through the medium of the handle 14, the molding'34, by reason of the frictional engagement of the rolls 17 and 20 therewith,

is advanced through the space between these rolls, and in this operation'its side members are spread to the desired angular position.

In the particular construction illustrated the portion of the member 5 which contains the front portion of the bore 30 is split, as

represented at 36, and cooperating with these split portions is a clamping device, represented at 37. The clamp, which isin the form of a stem, is provided at its lower end with a threaded-section 38, adapted to engage internal screw-threads 39 in the lower section of the split portions 36, this clamp being provided intermediate its ends with a shoulder 40 between which and the threads 38 the stem loosely passes through an opening in the upper portion of the split portions 36, whereby, upon rotating the stem 37 in one direction, the split portions 36 will be drawn together for tightly grip ping the sleeve 29, to hold it in adjusted position, and when rotated in the opposite direction will permit the split portions to spread, to release thesgrip on the sleeve 29.

In'ol'der to permit the operator to readily adjust the eccentricsleeve 29 to a position for spreading the sides of the molding to the desired angle, I provide the mechanism which is in the nature of a protractor, of

which the following is a description. I

Surrounding the sleeve 29'and rigidly sethe construction illustrated, formed of" a jac-ent the plate 42, the roll 20, by reason of the adjustment of the eccentric sleeve 29, with the plate 42, will extend at the proper distance above the roll 17 for spreading the sides of the molding 34 to a position wherein they will extend, relative to each other, at the angle indicated by the marking opposite the particular marking 45,0pposing the marking 46. Thus, for example,

assuming that the molding 34, the'sides of' which would be preliminarily and initially formed to extend at ninety degrees-toeach other, is to be spread to cause its sides to extend at an angle of one hundred degrees to each other, the operator, upon unloosening the clamp 37 to permit the sleeve 29 to be rotated, would rotate the plate42 and with itthe sleeve 29, to a position wherein the marking 45 opposite the numeral on the plate 43, would be in line with the marking 46, and

upon inserting the' molding into place between the rolls 17 and 20 and operating the shaft 1 0, as hereinbefore described, the molding would be spread to the desired angle of one hundred: degrees.

What I claim as new and desire to secure by Letters Patent is V 1. In a machine for the purpose of changing the angle of molding, the combination of a body-member containing a bore and slotted to providea split bearing, a shaft on said member, a roll on said shaft, a rotatably supported member in said bearing provided; with end-journals, a roll journaled in said last-named member on an axis eccentric of the axis of the latter and opposing said first-named roll, the axis about which said last-named roll rotates extend ing substantially parallel with said rolls,

said rolls being adapted to receive between cooperatingwith the stationary part of the machine for indicating the position of the rotatably supported roll, with reference to the other roll of the pair.

2. In a machine for the purpose of changing theangleof molding, the combination of a body-member provided with an open ing adjacent its lower end, a shaft extending through. said opening, a roll on said shaft,'a bore in said'body-memberadjacent its upper end, a slot in said body-member to provide a split bearing, a rotatably-supported member in said bearing and containing an eccentrically-disposed opening, a shaft journaled in said opening and supporting a second roll, the axis of said last-named shaft extending substantially parallel with the axes of said rolls whereby upon rotatably adjusting said last-named member said last-named roll is adjusted relative to its companion roll to vary the space between said rolls, said rolls being Copies of this patent may' be obtained for five cents each, by addressing the commissioner of Washington, D. 0."

adapted to receive between them the molding to be operated on, means engaglng the split portions of said body-member for releasably holding said rotatably-supported member in adjusted position, and a plate carried by said last-named member and provided with markings cooperating with a relatively stationary part of the machine 'for indicating the position of the adjustably-supported roll with reference, to the other roll of the pair.
